Review on Enhance Productivity with Mount-It! 4 Monitor Stand: Quad Desk Mount for Multiple Computer Screens, Adjustable Arms, VESA Compatible - Perfect for 19-32 Inch Monitors by Alicia Jones

This was disassembled but it was an easy process. The instructions were a little skimpy, but it's certainly doable. Don't panic if you have additional details. They offer more than enough consumables for almost any application. It's a lot stronger than I thought. It can easily support the weight of large monitors. Well made product.
